I'm sure I'm like a lot of people where I don't touch a lot of the pages that appear on the left list. Some of these are: Browse, Activity, Discover, Radio, Follow, Messages, entire "Your Music" section. All these combined with my 14 playlists + Starred, I have a scrollbar even if I have a small Play Now artwork (and I like it large) and I really don't like scrollbars.
What I'm proposing is in the options, a section to turn off pages. If a section has no active pages, it won't display at all (including the title).
My main reason behind this is because I really do not like going from Top Lists/Play Queue and having to scroll down to my playlists. I also have a 1920x1080 monitor so it's not screen size.
